2SK3161STR-E-VB Product details
Back to previous pageProduct introduction：
The 2SK3161STR-E-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. The Trench process balances low switching losses with high reliability, and the TO262 package strikes a balance between heat dissipation capability and ease of installation. The combination of 200V drain-source voltage, 35A current capability, and 50mΩ on-resistance makes it an ideal upgrade alternative to traditional TO220 or DPAK packaged devices, especially suitable for high-power-density applications such as industrial power supplies and motor drives.

VDS=200V: Suitable for 48V/72V/110V systems, providing ample voltage spike margin to reduce avalanche breakdown risk.
VGS=±20V: Compatible with 10V~15V gate drive, can directly connect to dedicated driver ICs or MCU driver stages, simplifying peripheral design.
Vth=3V (Typical): Moderate threshold voltage, strong anti-interference capability, while ensuring full conduction under standard gate voltage drive.
RDS(on)=50mΩ @ VGS=10V: Low on-resistance significantly reduces full-load temperature rise, allowing for smaller heatsinks or higher power density.
ID=35A: Ample continuous current margin to handle peak demands of most industrial and automotive loads.
Package TO262: Fully isolated pin design facilitates installation, large heatsink contact area suitable for long-term operation in high heat dissipation scenarios.
Domain and module applications：
Industrial Switching Power Supplies: High withstand voltage and low internal resistance improve conversion efficiency, reduce rectification stage losses, and aid in power module miniaturization.
Motor Drives and Inverters: Low PWM switching losses, suitable for 200V bus voltage, resulting in smoother motor operation and significantly reduced controller temperature rise.
Electric Vehicle Chargers and DC-DC Converters: Replaces high-voltage diodes in synchronous rectification, improving heavy-load efficiency by 2-3%, facilitating compact module design.
Battery Protection and Energy Storage Systems: Fast response ensures microsecond-level shutdown during overcurrent/short circuit, low internal resistance reduces self-heating of the protection board.
Photovoltaic Inverter Auxiliary Circuits: Voltage margin and wide operating temperature range (-55~150°C) adapt to harsh photovoltaic system environments, offering high reliability.
UPS Uninterruptible Power Supplies: High surge capability meets transient impacts during mains switching, low conduction losses extend battery backup time.
Automotive High-Voltage Load Management: Suitable for 12V/24V boost architectures and 48V mild hybrid systems, providing a robust solution for high-side switches. Selection Summary: 2SK3161STR-E-VB achieves a balance between voltage rating, on-resistance, and package heat dissipation. It is a cost-effective universal choice for 200V high-voltage switching applications, especially suitable for projects with strict requirements on power density and long-term reliability.
